[0002] This application is also a continuation-in-part of Application No. 10/892,816 filed on Jul. 16, 2004, which is hereby incorporated by reference in its entirety, which is a continuation-in-part of Application No. 10/623,179; filed Jul. 18, 2003, which is hereby incorporated by reference in its entirety, which claims priority of U.S. Provisional Application No. 60/396,850, filed Jul. 18, 2002, the content of which is hereby incorporated by reference in its entirety. BACKGROUND OF THE INVENTION [0003] The present invention relates to a method of surgical retraction. In particular, the present invention relates to a method of utilizing a table mounted retracting device during a surgical procedure on a hip of a patient. [0004] Total hip replacement (arthroplasty) operations have been performed since the early 1960's to repair hip components. These components include the acetabulum (socket portion of the hip) and the femoral head (ball portion of the hip). The hip is typically replaced due to a gradual deterioration of the cartilage that cushions the bones within the joint. The surrounding structures in the hip can become inflamed and painful. Eventually, bone can begin to rub against bone causing severe discomfort. [0005] Surgical procedures have been the most successful method to alleviate this pain. Either partial or total hip replacement surgery can be used. In total hip replacement, a cup shaped insert typically manufactured of polyethylene is inserted in place of the acetabulum, and a metal femoral head is placed in the femur. A number of variations have evolved in the surgical approaches and techniques used for replacement of the hip components, including operating while the patient is on his or her back (supine) or on his or her side (lateral). To a large extent, the choice of surgical approaches is due to the surgeon's preference as to what aspect of the hip components the surgeon wishes to view. The ability to view the surgical site is complicated by the need to remove the femoral head from the acetabulum as well as rotate and retract the femur in the wound during surgery. [0006] The surgical procedure can become quite physically taxing on the surgeon or surgeons performing it. The surgical procedure requires lifting and moving the patient's femur into multiple positions. At times, the surgeon may need to hold the femur in position for an extended period of time. Depending on the size of the patient, the strenuous activity can lead to fatigue and contribute to surgical error. Additionally, the repeated movement of the leg can cause nerve damage if it is not done precisely and with minimal adjustment. When the surgeon moves the femur by hand it is common to have continual adjusting occur. Often, the surgeon holding the leg relaxes or becomes fatigued and allows the leg to move, requiring that the leg be readjusted. The movement can cause the leg to pinch or rub nerves or muscle tissue, possibly causing damage. [0007] One way to reduce the physical nature of the operation and the number of personnel required to perform the procedure is to use retractors secured to a support that is secured to a surgical table to retract the flesh to expose the surgical site. U.S. Pat. No. 6,315,718 discloses a table mounted retractor system for a method of hip retraction. The table mounted retractor system includes using a table mounted support apparatus to support both flesh retracting retractors to expose the hip joint and bone retracting retractors to dislocate and displace the femural ball from the acetabulum. SUMMARY OF THE INVENTION [0008] The present invention includes a method of performing a hip joint surgery on a patient positioned on a surgical table where the hip joint includes a pelvis having an acetabulum, a femur and a femoral ball. The method includes mounting a retractor support to the surgical table. The retractor support is positioned about the hip joint and about an incision into the skin and flesh layers proximate the hip joint. A blade portion of a retractor is positioned within the incision and the skin and flesh layers are manually retracted proximate the hip joint. A handle portion of the retractor is pivoted with respect to the blade portion to position the handle portion in a selected position. The handle portion is secured in a selected position by attaching the handle portion to the retractor support. BRIEF DESCRIPTION OF THE DRAWINGS [0009] FIG. 1 is a top view of a surgical support apparatus positioned about a hip joint; [0010] FIG. 2 is a top view of a surgical support apparatus retracting a femur from an acetabulum in a pelvis; [0011] FIG. 3 is a top view of a surgical support apparatus wherein a prosthetic insert is inserted into the femur in the acetabulum of the pelvis; and [0012] FIG. 4 is a perspective view of a clamp having a clamping socket for securing a retractor handle therein. [0013] FIG. 5 is a top view of a retractor of the present invention. [0014] FIG. 6 is a side view of the retractor of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS [0015] The present invention relates to a method of performing surgical procedures on or proximate a hip joint. An apparatus used in the surgical procedures of the present invention is generally indicated at 10 in FIG. 1. [0016] The apparatus 10 includes a retractor support apparatus 12 that is rigidly mounted to a rail 11 of a surgical table 13 in a manner that is well known in the art and is described in U.S. Pat. Nos. 4,617,916, 4,718,151, 4,949,707, 5,400,772, 5,741,210, 6,042,541, 6,264,396 and 6,315,718 all of which are herein incorporated by reference. From the mount to the surgical table 13, the retractor support apparatus 12 includes left and right support arms 18 and 20 that extend over the surgical table 13. The support arms 18 and 20 are independently adjustable into an infinite number of selected positions through use of a clamping mechanism 22 which is described in U.S. Pat. Nos. 5,899,627 and 6,264,396, which are herein incorporated by reference. The support arms 18 and 20 extend in a substantially lateral direction over the surgical table 13 on opposite sides of a hip joint 30. The clamp 22 secures the adjustable support arms 18 and 20 in selected angular positions with respect to the hip joint 30. [0017] The surgical procedure on the hip joint 30 can be performed with any table mounted support structure and is not limited by the configuration illustrated and described herein. However, the table mounted support structure must provide support for mounting retractors to retract skin, muscle, blood vessels, tendons and bone while providing access to the hip joint 30. [0018] With the table mounted support structure 12 positioned in a selected position about the hip joint 30, an incision 32 is made through the skin. Typically, the incision is about six to eight inches long but may vary depending upon the surgical procedure being performed. [0019] After making the incision 32 through the skin, the surgeon divides the tissue, muscle, blood vessels and nerves to expose the hip joint 30 while causing minimal trauma. A lateral retractor 34 and a medial retractor 44 are positioned on opposite sides of the hip joint 30 to retract the tissue muscle, blood vessel and nerves and the retractors 34, 34 are attached to the support arms 18 and 20, respectively with clamps 40.
